1. A method of manufacturing a glass resin laminated body comprising: a step of sticking a glass film on a resin film via an adhesive layer while holding the glass film and resin film between a first roller that presses against the resin film and a second roller that is disposed opposite to the first roller and that presses against the glass film, wherein a thickness of the adhesive layer is less than or equal to 5 μm, a ratio of an elastic modulus P1 of a surface layer of the first roller to an elastic modulus P2 of the resin film P1/P2 satisfies a relation of 3×10−3≤P1/P2≤1.0, the surface layer of the first roller is formed of a material having an elastic modulus that is lower than the elastic modulus of iron, the surface layer of the first roller is a portion of the first roller 1 mm inward from a surface of the first roller towards a center; and the surface layer of the first roller is formed of a resin from a group consisting of polyethylene terephthalate, polyethylene, or polypropylene.
